It depends how thick your layer of paint is.
There is no universal conversion. A square metre is a measure of area while a litre is a measure of volume. The two measure different things and there is no simple way to convert from one to the other. The coverage will depend on the paint itself, the porosity of the surface etc. The can of paint will say what its coverage is likely to be. You may need to adjust for more porous surfaces.
A square unit is equal to 100 square feet so 2200 square units equals 220,000 square feet. One gallon of paint will cover approximately 400 square feet which means 550 gallons of paint are needed. If you plan on a double coat 1,100 gallons are needed. It will take 550-1,100 1 gallon cans of paint to cover 2,200 square units.
root 484 ie 22 feet
The answer depends on the preparation of the surface to be painted and on the paint, itself. Read the coverage information on the paint can.
About 8 liters for a smooth to semi smooth surface
That depends on how thick you paint, and how many layers of paint you use.
It depends how thick your layer of paint is.
It depends on the paint, and the surface that you are painting - including its preparation.
If your drum is a 55 gallon drum and your paint can cover 400 square feet per gallon then you may cover (one coat only) a square almost 150 by 150 feet.
Paint coverage depends on the type of paint (acrylic, alkyd, enamel, latex, etc.), the texture and absorbency of the surface to be painted, and the type of application (brush, roller, or spray). A first coat of paint usually requires more paint than a second or third coat because it reduces absorbency by making the surface smoother. Most paint manufacturers specify coverage for their paint to be somewhere around 8.6 square meters per liter, so it would probably take about 1.5 liters to cover 12.15 meters with a single coat.
About 1/80 of a litre - barely a touch out of the can.

A gallon of paint will cover about 300 square feetof wall area. So it will depend on the surface you are painting but in general square 5 gallons will cover approximately 1500square feet. Some manufacturers stretch ... If you can't decide between 4 or 5 gallons, go with 5 and buy it in a 5-gallon container. It should actually be cheaper than three 1-gallon cans, and you're guaranteed the colors will be the same.
Liters (L) i am pretty sure this is correct because in my chemistry class today we were talking about the ratio of liters of red and white paint to make pink. Hope that helped
Look on the paint tin. Different paints have different coverage which also depends on the surface being painted: its porosity, preparation and so on.
If you are thinking of paint (or something similar), you need to look at the tin to determine the coverage of the substance. That will also depend on the nature of the material that you are trying to cover - its porosity, for example.
